Those with a bent to become a literal Frosty the Snowman will want to check out TERA’s ongoing holiday event, the Wintera Snowfield Battleground. The special battleground is a snowball fight deluxe. Participants can earn holiday costumes including a Wintera scarf that transforms the wearer into a snowperson, Sleipnir and Snowdrift mounts, a snowsuit and more. The event runs through January 4, 2017.
